Ibn al-Athir

Ibn al-Athir held administrative positions in Mosul under the Zengid rulers, including serving as a vizier or secretary. This role gave him access to state archives and firsthand knowledge of political and military events he later chronicled.

Ibn al-Athir wrote a history of the Zengid dynasty, focusing on the reign of Nur al-Din and Saladin. This work provides detailed accounts of the Muslim counter-crusade, including the Battle of Hattin and the capture of Jerusalem.

Ibn al-Athir lived through the Mongol invasions of Persia and the Middle East, including the fall of Baghdad (1258) which he did not live to see. His chronicle records the destruction of cities like Nishapur and the massacre of populations, providing a contemporary account.

Ibn al-Athir compiled a biographical dictionary of the Prophet Muhammad's companions, listing over 7,500 entries. This work became a standard reference for Islamic biographical literature, organizing companions by name and tribe.

Ibn al-Athir finished his universal history, a multi-volume chronicle covering world history from creation to 1231. The work includes detailed accounts of the Crusades from the Muslim perspective, drawing on his own experiences and interviews with participants.
